Servo motor vs Stepper motor the 2 workhorse

Servo Tester.

First of all to understand the difference between servo motor vs stepper motor let us find how to test a servo motor. It is a very low-cost device at less than Rs 200/- absolutely required for testing small servo motors. It is. a must device for hobby robotics. It is basically to both test and ensures the center position ( at 90 degrees) of a (non-continuous spinning only ) small Servo Motor which is very important for robotic applications as, the unit that is procured from the market, its shaft may not be in the center position. Thus if used without fixing its shaft position in the center, for any robotic application, say a humanoid biped, hexapod, pick and place, gripper, claw, etc during assembling,  then it gives erratic operation at the time of switch on even if the programming is correct. 90-degree position of the shaft is the center position where from the non-continuous servo shaft moves exactly – 90 degrees ie to the left from center to zero and similarly + 90 degrees to the right from the center position to 180 degrees while right time period 1ms to 2ms train of pulses are fed to its sensing terminal as seen below. Thus it coves say from zero degrees to 180 degrees from full left to full right passing through the center.
